Speaking of home time control switches, I am afraid many friends do not know much about it. However, in recent years, time control switches have become a very common product for us. In fact, there are many brands of time control switches, among which CHINT time control switches are a very good choice. But readers, are you familiar with CHINT time control switches? In fact, the function of CHINT time control switches is very good. Many consumers like CHINT time control switches very much. Let's get to know them together.
Chint switch brand introduction
Chint Electric is one of the four pillar industries of Chint Group, along with high and low voltage electrical appliances, power transmission and transformation, and instrumentation. It is the first national electrician brand. , has been struggling in switches and sockets for many years, and may be recognized by consumers. Chint Switch's pursuit of quality has been recognized and applauded by consumers, partners, industry organizations and national institutions. It has won the honors of "China's Well-known Trademark", "China Electrical Equipment Industry Association Quality Trustworthy Product", etc., and was rated as "China's Housing Industrialization Base" by the Ministry of Construction.
The principle of CHINT time-controlled switch
When a general overload occurs on the line, although the overload current cannot cause the electromagnetic release to operate, it can cause the heating element to generate a certain amount of heat, prompting the double The metal sheet is heated and bent upward, pushing the lever to disengage the hook and the lock, disconnecting the main contacts and cutting off the power supply. When a short circuit or severe overload current occurs in the line, and the short circuit current exceeds the instantaneous trip setting current value, the electromagnetic release generates sufficient suction force to attract the armature and hit the lever, causing the hook to rotate upward around the rotating shaft seat and disengage the lock. , the lock breaks the three main contacts under the action of the reaction spring and cuts off the power supply.
When a general overload occurs on a line, although the overload current cannot cause the electromagnetic release to operate, it can cause the heating element to generate a certain amount of heat, prompting the bimetallic sheet to bend upward when heated, and push the lever to make the hook and the lock Disengage the buckle, disconnect the main contacts, and cut off the power supply.
When a short circuit or serious overload current occurs in the line, and the short circuit current exceeds the instantaneous trip setting current value, the electromagnetic release generates sufficient suction force to attract the armature and hit the lever, causing the hook to rotate around the rotating shaft base. Turn upward to disengage the lock. The lock separates the three main contacts under the action of the reaction spring and cuts off the power supply.
The tripping mechanism of the switch is a set of connecting rod devices. When the main contact is closed by the operating mechanism, it is locked in the closing position by the latch. If a fault occurs in the circuit, the relevant tripper will act to disengage the latch in the tripping mechanism, and the main contact will quickly break under the action of the release spring.
Large air switches also have overload protection, which generally uses bimetallic sheets. When the circuit is overloaded for a certain period of time, the heat will deform the bimetallic sheet and cause the release to trip. Disconnect circuit search.
Today, the editor has introduced so many CHINT time control switches to you. I believe that everyone has a certain understanding of CHINT time control switches. When choosing CHINT time control switches, you might as well consider the following: The editor introduces these methods to you. In fact, the treatment of CHINT time control switch is reliable, and it has always been the product chosen by many friends. We should know more about CHINT time control switch. It is very helpful for us to choose CHINT time control switch.
